UNITED STATES PATENT OFFICE.

G. H. MALLARY, OF NEWYORK, N. Y.

SHING-LE-MACHINE.

Specification of Letters Patent No. 17,104, dated April 21, 1857.

To all whom it may concern:

Be it known that I, G. H. MALLAEY, of the city, county, and State of NewYork, have invent'ed certain new and useful Improvements in Machineryfor Sawing and Planing Shingles; and I do hereby declare the followingto be a full, clear, and eXact description thereof, reference being hadto the accompanying drawing, in which- Figure 1, is a rear elevation;Fig. 2, a section. Fig. 3 is a plan; Fig. l the underside of the feedingapparatus.

My improvements are for the purpose of simplifying the working parts ofthe apparatus and causing more accuracy and durability therein, and inso arranging andcombining a saw and cutter as to properly operate uponthe shingle at the same time, the cutter or plane being made to vibrateso as to plane the shingle while sawing to the usual taper.

The construction is as follows: On suitable ways or rails a the carriageruns.

These rails a are connected with sufficientV framework to support themand the saw and plane hereafter described. The saw I) is an ordinarycircular saw of any kind known in the market, and runs in the mostapproved way for shingle sawing. Just in front of the saw o a littlebeyond the point where the saw cuts there is stationed a cylindricalcutter c in a vertical position .so as to work in the same plane as thesaw,

or rather in a plane at a suflicient angle thereto to plane the taper.This cutter is hung in a frame al that is made to slide in a right lineto and from the `line of the saw cut. This frame is most clearly seen inFig. 2. This frame is regulated in its distance from the cut by thecorner piece c on the sliding carriage embraced by the guide bar faliXed to the sliding carriage or frame d by which the movement of theframe 0l is made.

The carriage upon which the bolt g to be 4 sawed rests is made asfollows: A framework of oblong form h, 7L, runs on the rails 'madetherefor back and forth past the carpivoted at z". This has a shortvibration from side to side regulated by the two cam wheels la aiixed tothe frame h which bear against the rear end of the vibrating plate z' oneach side as shown by the dotted lines on Fig. 3. These two cam wheelsare turned by spring catches 7c on the stationary part of the machineagainst which they strike when the carriage runs back and both are thuslturned at once. This arrangement moves and holds the vibrating plate z'lirst on one side and then theV other which serves to form the taper onthe shingle. Upon this plate i there is afliXed sliding ways z'. Abovethese the slide plate m is put and moves in a line at right angles tothe carria-ge or up toward the saw. On the last named plate m arefixtures to dog the bolt in placehand on the underside there is a rack(seen in Fig. 2) into which a pawl n works. This pawl is attached to arod or slide n that as the carriage runs back strikes a stationary camon the frame at o and the slide plate m is thus driven forward. A springreturns the pawl back; the pawl is released by a rod attached at n2below. It will be noticed at each advance of thebolt it is rocked to oneside and then is properly presented to the saw. Instead of the two camwheels 7c one only may be employed at the center striking on each sideagainst a fork or pin. This is so obvious a change that no furtherdescription is necessary. It dispenses with one cam wheel and one spring7c.

I do not claim any of the separate parts composing this machine whenemployed by themselves, but

Vhat I do claim is- The arrangement of the several devices hereindescribed by which the bolt is sawed into shingles and planed as hereinset forth the whole being combined and constructed substantially asabove specied.

Gr. I-I. MALLARY.
